MBX5-truggy conversion, little advise

[wallot]

which motor do you plan to run? 2050kv? or more?

I use 1700kv on 5S lipo with 46/14 gearing and is ok for smaller tracks
for more open tracks i use 46/15

internal BEC is ok for one strong servo (6V/5A)

5S 3300mah hyperions will give me 10minutes of racing runtime
5S 5000mah zippy flightmax give me 15minutes

I only race with my mugen
